OK so I have selected the Lulzbot Mini for my next 3D printer purchase and I’m chomping at the bit to place the order yet there is just one final detail to get cleared up before ka-ching! Sold!
The issue is that my existing Printrbot Simple Metal is causing Cura to list a serial port error after running a print for some time between 15 and 45 minutes. It’s always the same error and it says this:
Recv: ok T:178.3 /0.0 B:0.0 /0.0 T0:178.3 /0.0 T1:26.4 /0.0 T2:43.2 /0.0 @:0 B@:0 Unexpected error while reading serial port: SerialException: 'read failed: [Errno 6] Device not configured' @ machineCom.pyo:_readline:576 Changing monitoring state from 'Operational' to 'Error: SerialException: 'read failed: [Err...' Connection closed, closing down monitor
I was using a long dangly USB cord with an extension USB cord which fit loosely into the printer. So I replaced the cord with a nice short one that fit properly into the printer. I have not yet printed for enough time to know wether or not this fixed it, but if it did I’ll feel confident in buying the Mini.
Why delay a Lulzbot purchase because of an error with a Printrbot? Because the Mini can ONLY print from the serial port. There is no SD card option. I would hate to ask my family to spend all that money on a printer plus accessories only to have to tell them that I STILL cannot print. That’s the situation, advice please?
